THREE-ROLLER SUGAR-CANE AND LIKE MILL.

Specification of Letters Patent.

Patented Aug. 11, 1914.

Application filed April 6, 1914. Serial No. 829,990.

To all whom it may concern:

Be it known that I, CHARLES MoNnIL, a subject of the King of Great Britain and Ireland, and a resident of Govan, in the city and county of Glasgow, Scotland, have invented certain new and useful Improvements in Three-Roller Sugar-Cane and like Mills, of which the following is the specification.

This invention has for its object to provide an improved form of roll housing or headstock for three-roller sugar-cane and like mills, in which while the parts are so disposed in regard to the stresses during work that great strength with a minimum of material is attained, at the same time the construction is such that the roll bearing caps are secured in position upon the housings without its being necessary to employ the usual lengthy king bolts passing through the housings.

According to the invention the outer ends of the usual housing gaps to receive the roll bearings have faces, either integral with the housing, or fixed thereto parallel with the axes of the rolls, and inclined to one another in suchwise that the space between their outer ends in the plane of the housing is less than the space between their inner ends. The caps have projections which extend into these gaps, and these projections have similarly inclined faces; that is to say, the inner ends of the projections are greater in width than the outer or root part of them which is next the cap proper. The gap faces and the cap faces may be counterpart, so that when the cap is slid laterally into the gap the faces engage to resist outward pressure from the rolls. Keys or the like may be provided to lock the parts in position. Or alternatively, the width of the cap projection may be less than the width of the gap projection and its faces be less inclined than the faces of the gap, thus permitting that the cap be placed in posi tion endwise. To secure it in position wedge blocks, having one face counterpart to the gap surface and the other counterpart to the cap surface, are inserted at each side and locked in position, for example by screw bolts passing through the cap. The two constructions are embodied in the mill shown in elevation in the accompanying sheet of drawings. On the right hand side of the mill the housing gaps have inclined faces A counterpart to inclined faces B on the inward projections C of the caps. In this case, the caps are slid laterally into position. In the example shown on the left hand side of the figure the space between the faces B on the caps is such an amount less than the space between the faces A in the gaps that the caps may be placed endwise in position. The faces A and the faces B are also of slightly different anglethat is to say if produced outwardly they will meet. Between them are counterpartly faced wedge blocks D operated to secure the caps in position by screw bolts E.

The housings may be castings as shown or may be built up of plates and beams.

What I claim is 1. In sugar-cane or like mills, housings having roll gaps comprising at their outer ends inclined faces parallel with the rolls and outwardly inclined toward one another, caps for the gaps, inward projections on the caps and correspondingly inclined faces on the projections.

2. In sugar-cane or like mills, housings having roll gaps comprising at their outer ends inclined faces parallel with the rolls and outwardly inclined toward one another,

caps for the gaps, inward projections on the caps, correspondingly inclined faces on the projections and means for securing the parts in position.

3. In sugar-cane or like mills, housings having roll gaps comprising at their outer ends inclined faces parallel with the rolls and outwardly inclined toward one another, caps for the gaps, inward projections on the caps, correspondingly inclined faces on the projections, the width of the projections being less than the least width of the gaps, and wedge blocks between the gap and cap faces for securing the parts in position.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.

CHARLES MoNEIL, B. So.
